     particles surface porosity is one of effective physical properties in flotation. to evaluate the effect of this parameter, the sample of quartz was ground by rod and ball mills and classified in the range of +250-300 microns. then different nanoscale and microscale surface porosity were made by contacting quartz particles with hydrofluoric acid in certain time. surface porosity measured by using scanning electron microscopy and image analysis software. experimental studies have shown that in optimum flotation conditions, increasing the surface porosity in mentioned range will greatly enhance recovery. also rod mill product has more recovery than ball mill product.
